BLOCKS USED AS BEDS lN PUNCHING AND CUTTING MACHINES AND IN CUTTING OUTGENERALLY.

SPECIFICATION forming part of Letters Patent No. 412,802, dated October15, 1889.

Application filed February 2, 1888. Serial No. 262,804 (No model)Patented in France May 3, 1887, No. 183,309 in England July 14, 1887,No. 9,910, and in Belgium November 1 1887, No. 79,528.

To all whom it may concern.-

Be it known that I, PIERRE JOSEPH SIMoU- LIN, a citizen of the Republicof France, have invented certain new and useful Improvements in BlocksUsed as Beds in Punching and Cutting Machines and Cutting Out Generally;and I do hereby declare that the following is a full, clear, and exactdescription of the same.

The invention has been previously secured to me in France by LettersPatent No. 183,309, dated May 3, 1887, and by a certificate of additionannexed thereto dated November 10, 1887; in England by Letters PatentNo. 9,910, dated July 14, 1887, and in Belgium by Letters Patent No.79,528, dated November 14, 1887.

My invention relates to an improved block used as a bed or underlay forpunching or cutting tools generally.

My invention consists of a block or sheet made of material composed inwhole or in part of dissolved nitro-cellulose. This substance is knownin the trade under various names; such as celluloic parkesine,

zylonite, and such like compounds having 'pyroxyline as a base.

The hereinbefore-described blocks or underlays are manufactured in thedesired shape and thickness by molding, shaping, or

otherwise. TV hen the blocks, after being used for a given length oftime, have been subjected to wear and tear which renders the replacingthereof necessary, they can be molded again into blocks or sheetswithout losing any of their properties; or the damaged surfaces may beeasily repaired by filling the cuts and holes with a liquid made bydissolving pieces of the very same blocks or underlays in alcohol,ether, acetone, or any other appropriate dissolvent, and adding theretoa small proportion of crystallized camphor, the said liquid mixturebeing applied. by means of a paint-brush, and then pressing the coatedblock between two iron plates, preferably steam-plates, to impartcomplete smoothness of surface.

The application of my invention to cutting beds for paper collars isshown in the annexed drawings, in which- Figure 1 is a plan of the bed Aprovided with my improvements, and having thereon a pile of material 1),adapted for making paper collars, and a cutter for cutting out the same.Fig. 2 is a section of the same on line 00 w in Fig. 1.

In one corner of the pile of material 13 is shown an aperture C, fromwhich a pile of collars has been cut, and adjacent to such aperture isshown the cutter D, resting upon the pile and adapted, when pressedthereon, to cut through the pile to the surface of the bed.

E is the block or sheet upon the wooden plank F to form a bed for theknife or cutter D.

The knife is shown resting upon the material B, and it is obvious thatif the bed, with the material and cutter, be inserted in a suitablepress the cutter could be forced through the material into contact withthe bed. The.

pressure required to sever the material would in many instances forcethe cuttingedge into the bed, and the surface of the latter would thusbecome marked and roughened by the knife and could be renewed in themanner described above.

The drawings are furnished only to'show a single application of myinvention; but it may be used in any other connection where acutting-bed is required to sustain the mate rial during the operation ofcutting bya knife or cutter forced through the material into contactwith the bed. 1

The patent issued upon my present application is limited in its durationby a prior French patent filed by me May 3, 1887 I claim- A Thecombination, with a knife or cutter, of

a block or sheet the base of which :is composed of solublenitro-cellulose, the knife be ing operated by pressing it through thematerial laid upon the block or bed and partly into the surface of theblock or shcet,substantially as herein set forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
